From 809a591b16781cc69f1f3ff2cc9a790e3ae8ec8f Mon Sep 17 00:00:00 2001 From: Roberta Dobrescu Date: Thu, 16 Apr 2015 22:20:58 +0300 Subject: [PATCH] staging: iio: light: isl29018: Rename lux_scale to calibscale This patch renames lux_scale to calibscale and lux_uscale to ucalibscale. This is done in order to avoid confusion since these parameters are used for hardware applied calibration.
